Introduction to the Bow Valley Parkway: The Bow Valley Parkway connects the towns of Banff with Lake Louise. Along the way there are many places like Johnston Canyon and Silver City, a ghost town in the 1800s. Award-winning interpretive exhibits and unique attractions like Silver City (Silver City) and the Hillsdale Slide offer glimpses of bighorn sheep on the cliffs and elk and wolves in the marshes. And because there are several of the most spectacular waterfalls in the area on both sides of Johnston Canyon, it has become one of the most popular hiking spots in Banff National Park.
